Impimi is a Polish brand and like Comexim I have heard that Impimi is able to make customizations to their bras. I contacted Impimi about possibly getting a bra to review. First they sent me 65G and 65H which should be equivalent to 30E and 30F (I also wear 65H or 70G in Comexim and both being Polish figured one of those should work, and 30E/F is my UK size).
